2 Claims.

My invention relates to a hair clipper and particularly to the cuttingplates or blades of such instrument.

Hair clippers now generally used have a pair of cutting blades eachprovided at the front edge with teeth or serrations, one of the bladesbeing stationary and the other movable. To cut the hair in differentlengths, it has heretofore been necessary either to change the blades orto use at least two clippers having blades of different thicknesses. Thesubject of the present invention relates particularly to theconstruction of the teeth of the cutting blades and involves suchformation of the teeth that they will cut the hair in varying lengths.

It is an object of my invention to provide blades for a hair clipperthat are adapted to cut the hair at the back and sides of the headaccurately, speedily, and in graduated lengths.

Another object is to provide cutting blades which can be used in asinglehair clipper to cut the hair to different lengths without necessity ofchanging the blades. 'A further object is to provide cutting blades thatmay be used interchangeably with the present blades in any standard formof hair clipper whether ofthe electrical or the hand operated types.

My invention is specifically limited to the construction and form of thecutting blades. I do not claim any invention in the mechanism foroperating the blades. However, it is to be understood that the bladesare to be used with a hair clipper having a suitable mechanism forgiving the movable blade the usual reciprocating movement.

In the drawing:

Figure 1 is a perspective view of a pair of cutting blades embodying myinvention;

Fig. 2 is a bottom plan view thereof; and

Figs. 3, 4, and 5 are cross-sectional views .of

I modifications of the same.

The drawing illustrates a pairof blades in which in represents thestationary plate and II the movable plate. The plates may be of anysuitable form to fit the clipper with which they movable plate. The twosets of teeth cooperate to shear or clip the hair upon reciprocating themovable plate.

The teeth of the stationary blade Ill each comprise an upwardly inclinedconnecting portion 5- l5 and downwardly extending tooth portion IS. Thetooth portion tapers uniformly in thickness from top to bottom, andpreferably terminates at its lower end in an overhanging beveled edge H.

The movable blade H has a corresponding set of teeth each comprising adownwardly inclined connecting portion l8 and an upwardly extendingtooth portion I 9 which latter portion may be of uniform thickness.

In the form of blades shown in Figs. 1 and 2, the outer faces of theteeth IQ of the movable plate contact throughout their lengths with theinner faces of the teeth I6 of the stationary plate so as to providelong, uninterrupted, shearing surfaces.

The hairs enter into the spaces between the teeth and are sheared orclipped in uniformly graduated lengths by reason of the tapering form ofthe downwardly extending teeth It of the stationary plate and theshearing action of the teeth l9 of the movable plate.

In the modification shown in Fig. 3, each stationary tooth I6 has arecess 2| in its inner face intermediate its ends, which recessinterrupts the shearing contact of the movable tooth l9 against theformer. Blades of this character are adapted for use to clip the hair todifferentlengths. In such use, the parts below the recess serve to clipthe hair finer, or to shorter lengths, while those above the recessserve to cut it coarser, or in longer lengths.

Fig. 4 illustrates a modification wherein the connecting portion 22 ofthe movable teeth l9 extends forward in theplane of the blade II insteadof being inclined downwardly as in the forms previously described.

-A further modification is shown in Fig. 5. In this instance the upperplate 23 is the movable platewhile the lower plate 24 is the stationaryone, both sets of teeth having downwardly inclined connecting portions25 and 26 respectively, and upstanding teeth 21 and 28 respectively. Itwill be noted that in this form the stationary teeth 28 are likewise oftapering form, being thicker at the top than at the bottom.

The construction of the plates is such that they may be readilyinterchanged with ordinary plates of the usual hair clipper, and whenapplied to a clipper maybe used to clip the hair in either direction,that is, up from the neck or down towards the neck. a

My improved hair clipper blades, because of the tapering form of theteeth, enable any person,

whether skilled or not, to cut hair accurately,"

speedily, and in proper gradation.

Having now described the nature of my invenand an elongated taperingtooth portion, and a movable plate having a series of teeth each ofwhich has a connecting portion and an elongated tooth portion, the outerfaces of the teeth portions of the movable plate being in shearingcontact with the inner faces of the teeth portions of the stationaryplate to clip the hair in graduated lengths.

Hair clipper blades comprising a pair of plates, one superposed onthe other, one of said plates having at its front edge a series ofelongated tapering teeth disposed in a plane at an angle to the plane ofthe plate, each tooth being thicker at one end than at the other, thesecond plate having a corresponding set of teeth arranged with theirouter surfaces in shearing con-
